Whether working at home or in the office, employees log in to the same network, work in the same applications, have the same human resources representatives, and share bosses.

Sharing a commitment goes beyond a boss unilaterally stating what the group should focus on. Instead, "the best teams invest a tremendous amount of time shaping a purpose that they can own."
Therefore, while groups rely on the individual contributions of its members, a team "strives for something greater than its members could achieve individually. In short, an effective team is always worth more than the sum of its parts."
Katzenbach and Smith cite three types of teams:
Creating a cohesive, productive team requires first determining what kind of team to be and what to work toward. That can be done by fostering an atmosphere of collaboration and teamwork, and continually adjusting goals and methods to ensure that the shared commitment remains.
